A self-portrait through 100 portraits, Artists Authors Thinkers Directors explores cartoonist Paul Hornschemeier's sketchbook renderings of those who shaped his (and many others) artistic views. These portraits are as stylistically varied as the subjects they portray. A scrawled, single line drawing of Lenny Bruce shares space with a triangular Werner Heisenberg. A monochromatic, stippled Stanley Kubrick stares intently at a muppet-headed Frank Oz. Each turn of the page offers a new take on a familiar face. In the afterword, Hornschemeier includes brief notes on each portrait and that creators particular work or insight that spoke specifically to him. And in that specificity, much of what is universally affecting in each creator shines through.

This book collects Paul Hornschemeier's sketchbook portraits of those who shaped his (and many others') artistic views, culled from his drawing blog The Daily Forlorn - spotlighted by Tumblr -- which adds thousands of new followers every week.
